Legendrian Hopf links in L(p,1)

Rima Chatterjee, Hansjörg Geiges, Sinem Onaran

We classify Legendrian realisations, up to coarse equivalence, of the Hopf link in the lens spaces L(p,1) with any contact structure.

Non-looseness of boundaries of Legendrian ribbons

Kenneth L. Baker, Sinem Onaran

Every null-homologous link in an oriented 3-manifold is isotopic to the boundary of a ribbon of a Legendrian graph for any overtwisted contact structure. However this is not the ca…

Strongly exceptional Legendrian connected sum of two Hopf links

Youlin Li, Sinem Onaran

In this paper, we give a complete coarse classification of strongly exceptional Legendrian realizations of connected sum of two Hopf links in contact 3-spheres. This is the first c…

Contact surgery graphs

Marc Kegel, Sinem Onaran

We define a graph encoding the structure of contact surgery on contact 3-manifolds and analyze its basic properties and some of its interesting subgraphs.

Contact surgery numbers

John Etnyre, Marc Kegel, Sinem Onaran

It is known that any contact 3-manifold can be obtained by rational contact Dehn surgery along a Legendrian link L in the standard tight contact 3-sphere. We define and study vario…

Minimal number of singular fibers in a nonorientable Lefschetz fibration

Sinem Onaran, Burak Ozbagci

We show that there exists an admissible nonorientable genus Lefschetz fibration with only one singular fiber over a closed orientable surface of genus if and only if $g \ge…
